About this study

New extended depth of focus intraocular lenses (IOLs) are being used in a broader spectrum of patients than trifocal IOLs. The purpose of this study is to evaluate visual improvement after cataract surgery in patients with glaucoma or ocular hypertension undergoing simultaneous cataract surgery with i-Stent implantation with the implantation of a Vivity IOL. Results will be compared with a group of glaucoma or ocular hypertension undergoing isolated cataract surgery with Vivity implantation, as well as with patients with no pathology undergoing cataract surgery and Vivity implantation

Read the detailed description

The purpose of this study is to report in detail visual function and patient satisfaction, as well as the need for spectacle correction, in patients with glaucoma and ocular hypertension undergoing cataract surgery with bilateral implantation of an extended depth of focus IOL, the Vivity IOL. The study also seeks to determine if there are differences in the speed of visual improvement between patients undergoing isolated cataract surgery and patients undergoing simultaneous i-Stent implantation. Results will also be compared with a group of patients with no ocular pathology undergoing cataract surgery with Vivity implantation.

Patients will be asked to join the study once the type of surgery (isolated phacoemulsification versus phacoemulsification combined with i-Stent implantation) and the type of lens to be implanted (monofocal, EDoF, trifocal) has been agreed between ophthalmologist and patient. Therefore, inclusion in the study will have no influence on surgical indication.

Once informed consent has been signed, the patient will be included in the study.

Explorations specific for the study will be performed 3 and 12 months after surgery and include:

Defocus curves Contrast sensitivity Self-reported photic phenomena Need for spectacle correction Satisfaction measured with the Catquest SF9 questionnaire

Besides study-specific procedures, the following explorations which are standard of care will be performed one day, one week and one month after surgery:

Uncorrected binocular visual acuity for distance, intermediate and near distances Monocular distance corrected and uncorrected visual acuity Residual subjective refraction Slit-lamp examination Intraocular pressure and number of hypotensive drugs required Description of any intra- or postsurgical complications

Questions about this trial

What is this clinical trial studying?

An observational study of Lenses, Intraocular and Glaucoma Filtration Implants, run by Clínica Rementería at 1 site in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 20 Jul 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Binocular uncorrected distance visual acuity (time frame: Three months after surgery). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Jul 2022.
